Abstract:
The prevalence of childhood obesity is increasing in South Africa and can be linked to decreased physical activity (PA). It is therefore important to be able to accurately measure children’s PA levels. The primary aim of this study was to determine whether children in grades two and three are able to self-report PA by means of a questionnaire. Fifty-eight participants (28 females, 30 males) from a primary school in Gauteng were recruited for the study. The participants had to wear a pedometer (Omron HJ-720) for seven days after which they completed the Physical Activity Questionnaire for older Children (PAQ-C). The average steps per day were 9289, with weekday steps (10 219) being more than weekend steps (6795). The mean (±SD) score for the PAQ-C was 3.14 ± 0.47. There was a significant moderate correlation (r = 0.49; p < 0.01) between the overall PAQ-C score and average steps per day. Therefore the PAQ-C can be an effective way in which to gain insight into PA levels in children but should not replace objective measures of PA. The participants in this study appear to be accumulating insufficient PA over the course of the week.
